$\huge \bold\color{maroon}☆A \color{red}n \color{indigo}s \color{purple}w\color{violet}e \color{pink}r☆$

Explanation:

The refractive index of diamond is 2.42. This means that the speed of light in a diamond will reduce by a factor of 2.42 compared to its speed in air.

● In other words, the speed of light in a diamond is 1/2.42 times the speed of light in a vacuum.
